Question

A small country is preparing for its anniversary, and a politician wants 2900 busts of the president for distribution. A copper alloy will be used, but the weight of the bust depends on the copper alloy. When the master of the bust is submerged in water, it displaces 0.00118 m3 of water. An 80-20% copper-zinc alloy requires $2.90 per kilogram for copper and $2.27 per kilogram for zinc. The densities of copper and zinc are 8,906 kg/m3 and 7,144 kg/m3 respectively. Your billing price is figured at six and one-half times the metal cost. The country's currency is renolas, figured at a current exchange rate of 13.4 units / U.S. $1. Find the price for 2900 units in renolas and U.S. dollars.
